Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25554, here are decompositions:

13 + 25541 = 25554
17 + 25537 = 25554
31 + 25523 = 25554
83 + 25471 = 25554
97 + 25457 = 25554
101 + 25453 = 25554
107 + 25447 = 25554
131 + 25423 = 25554

Showing the first eight; more decompositions exist.
